Roberto Vittori during a simulated pad emergency

CAPE CANAVERAL, Florida -- During a simulated pad emergency on Launch Pad 39A at NASA's Kennedy Space Center in Florida, STS-134 Mission Specialist Roberto Vittori, with the ESA, front, and a fellow crewmate make their way toward a slidewire basket that would take them to a safe bunker below the pad in an unlikely emergency situation. The emergency training while aboard space shuttle Endeavour is part of a week-long Terminal Countdown Demonstration Test (TCDT). Endeavour's six crew members are targeted to launch April 19 at 7:48 p.m. EDT. They will deliver the Express Logistics Carrier-3, Alpha Magnetic Spectrometer-2 (AMS), a high-pressure gas tank, additional spare parts for the Dextre robotic helper and micrometeoroid debris shields to the International Space Station. This will be the final spaceflight for Endeavour.
